Description
Technical field
The utility model relates to silicon chip of solar cell process equipment field, especially a kind of screen process press for printing solar cell backplate.
Background technology
Solar cell, after the operations such as making herbs into wool, diffusion and PECVD, has made PN junction, can generation current under light illumination, in order to the electric current that will produce is derived, needs on battery surface, make positive and negative two electrodes.The method manufacturing electrode is a lot, and serigraphy makes the most general a kind of production technology of solar cel electrode at present.Serigraphy adopts the mode of impression by predetermined graphic printing on substrate, and this equipment prints three parts by the printing of cell backside silver aluminium paste, the printing of cell backside aluminium paste and cell front side silver paste and forms.Its operation principle is: utilize silk screen visuals mesh through slurry, applies certain pressure with scraper at the slurry position of silk screen, moves towards the silk screen other end simultaneously.Slurry is expressed on substrate from the mesh of visuals by scraper in movement.Viscous effect due to slurry makes trace set within the specific limits, and printing middle scraper linearly contacts with substrate with screen printing forme all the time, and contact wire moves with scraper and mobile, thus completes print stroke.Main range of application is as follows: in (the p district) of cell piece, print electrode wire; Aluminum slurry is adopted to print front (except back electrode) in (the p district) of cell piece; ) print the uniform thin grid line in several rows of interval and main gate line in (the n district) of cell piece with silver paste.In silicon solar cell production, serigraphy is the important procedure producing solar cell, and its printing quality (thickness, width, thickness uniformity) affects the technical indicator of cell piece.
Screen printer has been the equipment of serigraphy, the existing screen process press for printing solar cell backplate, comprise frame, frame is provided with print station and printing frame, described printing frame is arranged on above print station, described printing frame is provided with half tone and frictioning frame, described frictioning chord position is above half tone, described half tone comprises silk screen and the frame for fixing silk screen, described silk screen upper surface scribbles one deck light-sensitive surface, described light-sensitive surface is provided with electrode hole, existing electrode hole is all generally directly arrange three electrode holes parallel to each other, the silicon chip back side be printed to can form three strip electrodes parallel to each other, the two ends of each strip electrode all extend to the marginal position of silicon chip, it is exactly that required back silver paste is more that this mode exists a larger problem, cause the production cost of silicon chip higher, secondly, the frictioning frame of existing screen printer comprises a moveable expansion link, the end of expansion link fixes a gripper shoe vertically arranged, a lower end directly bonding rectangle adhesive tape of gripper shoe, there is following problem in use in the frictioning frame of this structure, because rectangle adhesive tape is softer, and rectangle adhesive tape is the lower end being bonded in gripper shoe, like this in the process of frictioning, the active force of gripper shoe can only act on the upper end of rectangle adhesive tape, because adhesive tape is softer, when frictioning, adhesive tape easily produces larger distortion, not only affect printing quality, also greatly can shorten the service life of adhesive tape simultaneously, need to change adhesive tape frequently, time-consumingly to require great effort again, the fixed form of existing half tone is varied, but all there is the reason of installing/dismounting inconvenience, its reason is exactly to ensure after installing/dismounting that half tone is in original position, cause, the silicon chip surface of front and back printing is inconsistent, affect the crudy of silicon chip, operating personnel need repeatedly to debug the half tone after just can making replacing and are in the position changing front half tone, cause labor intensity of operating staff larger, in addition, existing half tone is mostly adopt non-removable mode when fixing silk screen, although the quality of printing can be ensured like this, but, obviously be less than the service life of frame the service life of silk screen, changing silk screen once needs just needs connection frame to change together, causes unnecessary waste, be exactly existing screen printer be in addition all manually add slurry in printing process, this not only human cost is higher while, manually time-consumingly when adding slurry to require great effort again.
